This application claims priority to U.S. Provisional Application No. 62/269,265, filed 18 Dec. 2015, the entire disclosure of which is incorporated herein.

FIELD

Embodiments of the subject matter disclosed herein relate to sensors used to monitor operational characteristics of powered systems, such as vehicles.

BACKGROUND

Various systems can include sensors for monitoring characteristics of the systems and/or surroundings of the systems. For example, vehicle systems, stationary power systems, etc., can include several sensors monitoring the same or different characteristics. These sensors can monitor vibrations, temperatures, states, or the like, of the systems in order to track operation of the systems, identify unsafe conditions, determine when maintenance or repair of the systems are needed, or to achieve other objectives. The data provided by the sensors may be used for one or more purposes to control operation and/or monitor health of the vehicles.

The accuracy of the measurements provided by sensors can depend on the locations of the sensors in the powered system. For example, a temperature sensor may provide more accurate temperature measurements of a location in a powered system when the sensor is closer to the location than when the sensor is located elsewhere in the powered system. As another example, an accelerometer can provide more accurate measurements of movement of a component in a powered system when the accelerometer is closer to and/or connected with the component than when the accelerometer is farther from and/or separated from the component.

But, some powered systems provide little to no room for sensors in some locations. For example, while it may be desirable to place a temperature sensor, accelerometer, or other type of sensor in a location onboard a vehicle that is on or close to the interface between the wheels and the route being traveled upon, there may not be room for placing sensors in this location. Moreover, the extreme conditions experienced by these locations can limit or prohibit the addition of sensors in the locations.

DETAILED DESCRIPTION

One or more embodiments of the inventive subject matter described herein provide sensor assemblies and methods that can monitor movement (e.g., vibrations) of one or more components of vehicles. In one embodiment, the assemblies and methods provide for sensors mounted to motor assemblies of vehicles to measure vibrations of the motor assemblies. The measured vibrations can be used to identify damage to bearings of the motors in the motor assemblies, predict when damage will occur to the bearings, or the like. The severe environment of wheel/axle combinations in vehicles (such as locomotives) can cause bearing failures in the traction motors to be a significant disruption to railroad traffic. Monitoring bearing health is a cost-effective solution to reduce the impact of these failures.

In one aspect, the assemblies and methods described herein provide integrated sensor housings that allow a sensor to be mounted to a U-tube structure of a motor housing without alterations to the existing U-tube or motor housing structure. The sensor assembly can mount to the U-tube structure using an existing opening, such as a jacking hole that is otherwise used to insert a jack for lifting the motor assembly. This type of mounting allows for a quick one-bolt installation without the need for drilling or welding on the existing structure of the motor assembly. The direct connection to the U-tube allows direct transmission of both vibration and thermal signatures of the motor assembly to the sensor assembly, where more accurate measurements of vibrations and/or temperatures may occur relative to placing the sensor assemblies in other locations.

FIGS. 1 through 7 illustrate one embodiment of a sensor assembly 100. FIG. 1 illustrates a perspective view of the sensor assembly 100, FIG. 2 illustrates a front view of the sensor assembly 100, FIG. 3 illustrates a rear view of the sensor assembly 100, FIG. 4 illustrates a top view of the sensor assembly 100, FIG. 5 illustrates a bottom view of the sensor assembly 100, FIG. 6 illustrates a left view of the sensor assembly 100, and FIG. 7 illustrates a right view of the sensor assembly 100. The sensor assembly 100 includes a housing 102 that extends from an insertion end or surface 104 to an opposite coupling end or surface 200 (shown in FIG. 2). The housing 102 also extends from a sensor end or surface 106 to an opposite back end or surface 300 (shown in FIG. 3), and from a first end or surface 108 to an opposite, second end or surface 202 (shown in FIG. 2).

The housing 102 includes a connector channel 110 that extends through the housing 102 from the insertion end 104 to the coupling end 200. In one embodiment, the connector channel 110 is a hole extending through the housing 102 that does not include a threaded surface (e.g., the channel 110 is threadless). Alternatively, the connector channel 110 may include one or more threads. As described herein, a connector may be inserted through the connector channel 110 and coupled with a motor assembly to secure the sensor assembly 100 to the motor assembly. The connector may be a threaded connector that is secured to the motor assembly by a threaded connection. The connector channel 110 may not have threads so that the orientation of the sensor assembly 100 can be controlled by an operator installing the sensor assembly 100 regardless of the relative positions of the threads on the connector and the threads on the motor assembly.

The housing 102 includes a sensor dish 112 extending outward from the sensor end 106. The sensor dish 112 includes a relatively shallow container of the housing 102 that holds one or more sensors in the housing 102. The sensor dish 112 extends from a front end or surface 114 to an opposite, back end or surface 302 (shown in FIG. 3) along the same or similar direction that the housing 102 extends from the sensor end 106 to the back end 300. The sensor dish 112 may have a circular side wall 116 that extends from the front end 114 to the back end 302. Alternatively, the sensor dish 112 may have another shape or size. The sensor dish 112 may be relatively shallow in that the distance from the front end 114 to the back end 302 may be smaller than the distance between any two opposite ends of the housing 102.

A radio frequency (RF) transparent sensor cap 118 is connected with the front end 114 of the sensor dish 112 to enclose the sensor or sensors within the sensor dish 112 by several connectors 120, 122. The sensor cap 118 may protect the sensors in the sensor dish 112 from damage and external environmental conditions, such as dirt, dust, moisture, and the like. The RF transparent cap may allow RF transmissions to pass through the sensor cap with minimal or reduced signal attenuation (e.g., relative to other types of materials).

FIG. 8 illustrates a perspective view of the sensor assembly 100 shown in FIG. 1 with the sensor cap 118 removed according to one embodiment. FIG. 9 illustrates the right view of the sensor assembly 100 shown in FIG. 1 with the sensor cap 118 removed according to one embodiment. FIG. 10 illustrates a front view of the sensor assembly 100 shown in FIG. 1 with the sensor cap 118 removed according to one embodiment. The sensor dish 112 of the housing 102 includes an internal chamber 800 where one or more sensors 1000, 1002 (shown in FIG. 10) of the sensor assembly 100 may be located. The internal chamber 800 is enclosed by the housing 102 and the sensor cap 118 when the sensor cap 118 is coupled with the sensor dish 112. While two sensors 1000, 1002 are shown in the illustrated embodiment, alternatively, a single sensor or more than two sensors may be included in the sensor assembly 100. The sensor 1000 may represent a temperature sensor, such as thermocouples or other temperature sensitive elements connected with hardware circuitry that includes and/or is connected with one or more processors (e.g., field programmable gate arrays, integrated circuits, microprocessors, or other electronic logic-based devices). The sensor 1002 may represent a movement sensor, such as an accelerometer or other device that senses movements (e.g., vibrations). The sensor 1002 may be connected with the same or different hardware circuitry as the sensor 1000.

The housing 102 may be formed from one or more materials that are sufficiently rigid and durable to permit the housing 102 to be detachably coupled with a vehicle moving along a route while also protecting the sensors 1000, 1002 disposed in the housing 102. In one embodiment, the housing 102 may be formed from cast steel, such as carbon steel. Alternatively, the housing 102 may be formed from another material. The housing 102 may be relatively large to hold the sensors 1000, 1002 while providing protection to the sensors 1000, 1002. In one embodiment, the housing 102 is approximately five inches long by three and a half inches wide by three and a half inches tall. For example, the housing 102 may be 5.16 inches by 3.625 inches by 3.5 inches. Alternatively, the housing 102 may have one or more other dimensions.

Communication circuitry 1004 may be included in the sensor dish 112. The communication circuitry 1004 can include or represent transceiving or transmitting circuitry, such as a wireless antenna, power source (e.g., battery or connection to an external power source), modem, etc., for wirelessly communicating the data output by the sensors 1000, 1002. The communication circuitry 1004 may communicate the data output by the sensors 1000, 1002, such as the measured temperatures and/or vibrations, to one or more locations outside of the sensor assembly 100, such as a control system that controls movement of the vehicle to which the sensor assembly 100 is connected, a handheld reader that an operator uses to acquire the measurements from the sensors 1000, 1002, one or more wayside devices disposed on or alongside a route for reading data from the sensors 1000, 1002 as the vehicle passes over or by the wayside devices, etc.

FIG. 11 illustrates a motor assembly 1100 according to one embodiment. The motor assembly 1100 may be included in a vehicle, such as a rail vehicle, to generate tractive efforts that propel the vehicle. Alternatively, the motor assembly 1100 may be included in another type of vehicle. The motor assembly 1100 includes a motor 1102, such as a traction motor, that generates torque to rotate an axle 1104 connected with one or more wheels 1106 of the vehicle. The torque generated by the motor 1102 rotates the axle 1104 and wheels 1106 to propel the vehicle.

The motor assembly 1100 includes a U-tube structure 1108 on the exterior of the motor assembly 1100. The U-tube structure 1108 may be used to lift the motor assembly 1100 from the ground, as described below. In one embodiment, the sensor assembly 100 may be connected with the U-tube structure 1108 of the motor assembly 1100 to measure temperatures and/or vibrations of the motor assembly 1100 during movement of the motor assembly 1100.

FIG. 12 illustrates the U-tube structure 1108 of the motor assembly 1100 shown in FIG. 11 according to one embodiment. The U-tube structure 1108 includes a U-tube 1200 with a jacking hole 1202 disposed between the U-tube 1200. The jacking hole 1202 is an opening into the U-tube structure 1108 that a jack may be inserted. The jack can be inserted into the jacking hole 1202 in order to lift the motor assembly 1100. During movement of the vehicle that includes the motor assembly 1100, the jacking hole 1202 is not used and may be empty. At least one embodiment of the sensor assembly 100 described herein may be connected to the motor assembly 1100 in the jacking hole 1202. In one embodiment, the size of the channel in the housing 102 of the sensor assembly 100 is sufficiently large to allow for a screw or bolt that meshes with the threads of the jacking hole 1202 to pass through the channel. For example, the channel may have a diameter of at least 1.25 inches to permit a bolt having a diameter of 1.25 inches to pass through the channel. Alternatively, the channel may have a diameter of at least 1.375 inches (or another size) to allow for some clearance between the channel and the bolt.

FIG. 13 illustrates an exploded view of the sensor assembly 100 and a connector 1300 used to couple the sensor assembly 100 to the motor assembly 1100 shown in FIG. 11 according to one example. The connector 1300 may be an elongated bolt or other device that extends through the connector channel 110 of the sensor assembly 100. The connector channel 110 may have an axis 1304 that the connector 1300 is inserted along into the sensor assembly 100. In the illustrated embodiment, the connector 1300 includes one or more threads 1302 for securing the connector 1300 to one or more corresponding threads in the jacking hole 1202 (shown in FIG. 12) of the motor assembly 1100. As described above, the sensor assembly 100 may not include threads that engage the threads 1302 of the connector 1300. Instead, the sensor assembly 100 may not be secured to a particular location or orientation around the circumference of the connector 1300. This can enable an operator to change the orientation of the sensor assembly 100 relative to the motor assembly 1100 by rotating the sensor assembly 100 around the connector 1300 and the axis 1304. The connector 1300 can engage with the threads in the jacking hole 1202 to secure the sensor assembly 100 between a head 1306 of the connector 1300 and the U-tube structure 1108.

In one embodiment, the housing 102 and the sensor dish 112 are integrally formed from a common material (e.g., steel), and the channel 110 has a diameter of at least 1.25 inches and a shank (e.g., elongated body that does not include the head) of the connector 1300 corresponds in size to the diameter of the channel 110.

FIG. 14 illustrates the sensor assembly 100 connected to the U-tube structure 1108 of the motor assembly 1100 shown in FIG. 1 according to one embodiment. As shown in FIG. 14, the connector 1300 is connected to the U-tube structure 1108 through the jacking hole such that the sensor assembly 100 is held between the head of the connector 1300 and the U-tube structure 1108. The sensor assembly 100 is secured to the U-tube structure 1108 such that vibrations, temperatures, or other conditions of the U-tube structure 1108 and/or the motor assembly 1100 are experienced and/or measured by the sensor assembly 100.

FIG. 15 illustrates operation of the sensor assembly 100 according to one embodiment. The sensor assembly 100 is connected with the motor assembly 1100 and senses vibrations, temperatures, or other conditions of the motor assembly 1100 during operation of the motor assembly 1100 (e.g., during travel of the vehicle that is propelled by the motor assembly 1100). The sensor assembly 100 may wirelessly communicate the sensed conditions of the motor assembly 1100 to one or more monitoring devices 1500, such as a wireless gateway. The wireless gateway can include or represent hardware circuitry that includes and/or is connected with one or more processors (e.g., field programmable gate arrays, integrated circuits, microprocessors, or other electronic logic-based devices). The monitoring device 1500 can be onboard the vehicle that includes the sensor assembly 100 or may be off-board the vehicle. The monitoring device 1500 can use the sensed conditions to control operation of the vehicle, to determine if a component (e.g., motor) is damaged, to predict damage to the component, etc.

FIG. 16 illustrates a flowchart of one embodiment of a method 1600 for providing a sensor assembly. The method 1600 may be used to provide (e.g., manufacture) the sensor assembly 100 described above. At 1602, one or more sensors are positioned inside an internal chamber of a housing. The sensors may be capable of measuring operational conditions or characteristics of a vehicle, such as vibrations, temperatures, etc. The housing may include a radio frequency (RF) transparent component (e.g., cap) to allow for wireless communication of data to and/or from the sensors inside the housing. This can allow for the sensors to remain protected from external conditions while the sensors communicate data indicative of sensed conditions or operations to one or more locations outside of the housing.

At 1604, a threaded connector is placed through a channel in the housing without the housing having a threaded engagement with the connector. The channel may be an opening through the housing that does not include corresponding or matching threads. This allows for a threaded connector to extend through the channel without being secured to the housing in any particular orientation. For example, the housing can rotate around the connector and/or the connector can rotate within the housing without the housing rotating the connector or the connector rotating the housing. At 1606, the housing is secured to the vehicle by coupling the connector to the vehicle. The threads of the connector may engage corresponding threads in or on the vehicle to secure the connector to the vehicle and to secure the housing against the vehicle. Because the connector extends through the housing without the threads of the connector being coupled with threads of the housing, the housing is free to be moved relative to the connector to ensure that the sensors are positioned for sensing the operational conditions of the vehicle while remaining secured to the vehicle.

In one embodiment, a sensor assembly includes a housing extending from an insertion end to an opposite coupling end, extending from a sensor end to an opposite back end, and from a top end to an opposite bottom end. Each of the sensor end, the back end, the top end, and the bottom end intersects both the insertion end and the coupling end. The housing also includes a channel extending through the housing from the insertion end to the coupling end. The channel is configured to receive a connector that extends through the channel and connects with a vehicle to secure the housing to the vehicle.
